Midtown East, Manhattan, New York City
In terms of high-design pedigree, it's hard to ask for more. The squad behind the Four Seasons' look reads like a laundry list of visionaries. I.M. Pei -- the legendary architect behind the Louvre Pyramid in Paris, the Bank of China Tower in Hong Kong, and the east building of the National Gallery of Art in Washington, D.C. -- designed the public areas with 33-foot ceilings, rigorous symmetry, and a whole lot of limestone. The lobby and guest rooms owe their look to Remedios Siembieda, the designers behind interiors at high-end hotels from Hong Kong to Munich to Bora Bora.
